HABMAP Multi-beam Survey Coverage Areas

Areas of fine-scale Bathymetric and relative acoustic Backscatter data produced using a mounted Geoswath 125KHZ Interferometric sidescan sonar system, by the HABMAP program. Data is collected using a pole mounting and are tide, sound velocity and motion corrected and are accurate to the sub-metre level (DGPS/POSMV). The HABMAP program, which was initiated to provide fine scale benthic habitat information for NSW State Waters, initiated surveys to provide a minimum of 5 x 5m bin scale bathymetric and backscatter layers for use in GIS applications.\r\nMutlibeam data for each of the Survey Coverage Areas is downloadable from the Australian Oceanographic Data Network - https://portal.aodn.org.au/.\r\nSearch for: NSW Office of Environment and Heritage (OEH) Multi-beam Bathymetry Surveys \r\nAdditional information available at https://catalogue-imos.aodn.org.au/geonetwork/srv/eng/metadata.show?uuid=60160b01-8ffc-45ce-a6f4-ee70ce391ec6

本数据集由HABMAP计划（HABMAP program）采用搭载式Geoswath 125千赫干涉式侧扫声呐系统采集，包含精细尺度水深测量（Bathymetric）与相对声学后向散射（acoustic Backscatter）数据。数据采用杆式安装方式采集，经潮汐、声速与运动校正，精度可达亚米级（差分全球定位系统(DGPS)/POSMV）。该计划旨在为新南威尔士州（NSW）海域提供精细尺度底栖生境信息，其开展的调查作业可生成至少5×5米格网尺度的水深测量与后向散射图层，供地理信息系统(GIS)应用使用。
各调查覆盖区域的多波束测深数据可从澳大利亚海洋学数据网络（Australian Oceanographic Data Network）下载，下载网址：https://portal.aodn.org.au/。
